Offered in a two-chip set, Samsung's newest S3C2680/ S5M8311
WUSB solution enables high definition content to be wirelessly
transmitted from a mobile host device to a tethered device for
viewing. Initial applications are high-resolution cameras,
camcorders, TVs and PCs with prospects for adoption in other
applications including tablet PCs, printers, beam projectors,
portable HDDs, Blu-ray players, and mobile handsets.

"The ability to handle wireless high-speed data transmission
while consuming less power is a key requirement for many
consumer electronic devices," said Yiwan Wong, vice president,
System LSI marketing, Samsung Electronics. "Due to
power/performance issues, previous generations of WUSB products
were unable to meet the consumers' expectations. Samsung's new
WUSB chipset delivers up to 480Mbps (Megabit per second) data
transmission rate, at an average power consumption of less than
300mW. This level of power efficiency greatly increases the
attractiveness of WUSB connectivity in consumer electronic and
mobile applications"

Manufactured using its 65nm low power logic process technology,
Samsung's new WUSB chipset is a combination of a system-on-chip
(SoC) baseband processor and an RF transceiver. The new
solution can be applied in an SD card form factor, in USB
dongles, or embedded in consumer and mobile applications. It
allows wireless transmission at an actual information
throughput rate of over 200Mbps with power efficiency ten times
greater than that of the 802.11g WiFi standard. With
multi-threshold support, this new chipset also has decreased
power consumption by 30 percent over current WUBS available on
the market today.

With an embedded NAND flash memory controller built-in,
Samsung?s new WUSB chipset is the only product in the market
that can support WUSB-enabled SD cards. This type of
WSUB-enabled SD card allows pictures and video captured with a
digital camera or camcorder to be transmitted wirelessly from
the device to a host computer, a TV or a PC monitor for viewing
without any wire connections to download the contents from the
SD card.

Leveraging an ARM 9 core, Samsung?s WUSB chipset features
WiMedia v1.2 PHY and also has various interfaces such as SDIO,
SD card, SD host, as well as a NAND flash controller and two
high-speed USB 2.0 PHYs. This chipset solution also has a
128-bit AES encryption algorithm for secure data transmission.

Samsung?s S3C2680/S5M8311 WUSB chipset is now sampling to
select customers, and it is slated for mass production in the
fourth quarter of 2010.
